Title: Stored-information communication system
Inventor: SHIMADA HIROICHI
IPC: H04L12/70
Filed: 1980-07-30
Abstract: PURPOSE:To reduce the required numbers of circuits and processors by forecasting information and a time zone which are both high in frequency of utilization and by transferring and storing information from a center to a local station only in the forecasted time. CONSTITUTION:An information request signal from a user terminal 11 is sent to a central office center 21 via a subordinate station 13 to access required information. The station 13 analyzes the time and contents of the access statistically to send a request for information transfer to the central office center 21. Information high in freqency of use is transferred from the data bank of the central office center 21 to the station 13 in a time zone high in frequency of use. If the access from the user terminal 11 is in the station 13, access to the central office center is unnecessary. As a result, circuits and the processing of the central office center are reduced.

IPC: H04N1/04
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive image sensor unit which can increase the image reading speed without lowering the output level of a photoelectric transform signal by starting the driving of a light irradiation means of the unit together with a photoelectric transducer and ending the driving of the light irradiation means when the photoelectric transform signal is inputted from the photoelectric transducer. SOLUTION: The optical carriers which are generated by the photoelectric transform of the photodiodes PDa-PDd of photodetectors a1-ad undergo the electric charge/voltage transform via the MOS source followers M3a-M3d and are transferred to the storage capacitros Ca-Cd by a signal transfer pulse ϕT with coincidence of all pixels. Then the read switches M1a-M1d are sequentially turned on by the read pusels ϕa1-ϕd1 which are sent from a shift register 11 and sequentially set at high levels, and the signal voltage is read out on a common signal line 14 as the division of capacity. In a high resolution mode, the pulses ϕa1-ϕd1 are sequentially turned on and the adjacent pulses ϕa1 and ϕb1 are simultaneously turned on in a low resolution mode. Then the pulses ϕc1 and ϕd1 are simultaneously turned on.
